Ejection Seat replacement work

Ejector seats being removed from a MiG-21US (U655) for regular servicing. This version of the MiG-21, known to the Indian AF as the Type 66-600 series and distinguished by its broader chord vertical tail surfaces and 'acorn' parabrake fairing at the base of the rudder, is equipped with a damage simulator which is operated by the instructor from the rear seat.
